Alvarado orders his ship upstream at the Papaloapan River, leaving the rest of the small fleet behind to wait for him at the river mouth.

This action greatly angers Grijalva, who fears that a lone ship could be lost.

After this, the Spanish refer to the river as the Río de Alvarado ("Alvarado's River").

A little further along the coast, the fleet encounters settlements under Aztec dominion, and is met by Aztec emissaries with gifts of gold and jewels sent by the Emperor Moctezuma II.
